Berthold Stoeger 790d2b2ddb statistics: convert QuartileMarkers to QSGNodes
Slowly converting the QGraphicsScene items to QSGNodes to
avoid full replot of the scene.

This adds a new abstraction for line-nodes. Since the render()
function here is fundamentally different from the pixmap-nodes
we had so far, this has to be made virtual.

Also, move the quartile markers to their own source file,
since the StatsView source file is quite huge already.
